to the accompanying drawings.

This invention comprehends certain new and useful improvements inthreshing machines, and relates particularly to means for raising andlowering the body framework relative to the axles.

Threshing machines often have to be placed upon uneven ground andordinarily the machines are simply jacked up. This not, only takes timebecause the machine .must remain inoperative while being jacked up, butthe machine is supported in an unstable manner and altogether the use ofjacks has been found extremely unsatisfactory.

The general object of my invention is to provide improved means forleveling the body framework of the machine relative -to the axles and afurther object is to provide means whereby the forward ends of the bodymay be raised or lowered, said means including a screw, which acts asthe king pin for the fifth wheel of the front axle.

A further object is to so construct the leveling devices that theframework will be held securely in place when leveled and Without anydanger of the machine tilting over or of the axles turning or brealn'ng.

And the invention also aims to generally improve devices of thischaracter so as to render them more useful and commercially desirable. iI

With these'and other objects in view, as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combina tions of the parts that I shall hereinaftermore fully describe and claim. I

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which 4 Figure 1 isa side elevation of a threshing machine framework and running gearembodying the improvements of my invention,

Fig. 2 (\Sheet 2) is an enlarged vertical sectional view of the raisingand lowering device for the front end of the framework,

Fig. 3 is an inverted-plan view of the upper fifth wheel member,

Fig. 4 is a vertical sectional view through one of the devices forelevating the rear end of the framework,

Fig. 5 (Sheet 1) is a detail view of one of the framework bracketsemployed,

Fig. 6 is a transverse sectional view therethrough, and

Fig. 7 is a fragmentary sectional view illustrating the clamping devicefor the brace hereinafter specifically described.

Corresponding and like parts are referred to in the followingdescription and designated in all of the views of the accompanyingdrawing by like reference characters.

Referring to the drawings, A designates the body framework of athreshing machine as a whole, B the rear axle, G the front axle, and Dthe fifth wheel.

In carrying out my invention, the lower member or bolster plate 1 of thewheel D is formed on opposite sides with depending ears 2 that arelaterally spaced from each other and within which fits an apertured boss3 that is formed on a casting or bracket 4: adapted to be clamped to thefront axle C in any desired way. A pivot pin 5 extends transverselythrough the apertured ears 2 and boss 3, as shown, whereby the castingor bracket 4 is pivotally connected to the fifth wheel to permit theaxle to rock laterally as required.

A screw-threaded and vertically extending standard 6 is swiveled at itslower end as at 7, in the lower fifth wheel member 1 and extendsupwardly therefrom and engaged in and extends through a nut 8 carried byand I preferably embodied in the upper fifth wheel member or bolster 9,the latter being preferably formed with a tubular extension 10 designedto serve as an additional bearing for sald standard. The upper fifthwheel member or bolster plate 9 is connected in any desired wa to thebody frame work A as, for examp e, by the upwardly diverging supportingbars 11. Preferably a tail nut or look washer 12 is mounted upon thescrewthreaded standard 6 above the tubular bearmg extension 10 and isdesigned for engagement therewith to hold the standard againstaccidental turning movement after the ole sired adjustment has beeneffected, and the standard is formed at its upper end with any desirednumber of openings 13 to receive the rod 14: whereby the standard may beeasily turned.

From as much of the description as has preceded in connection with thecorrelated views of the accompanying drawings, it is evident thatwhenever it is desired to raise or lower the body framework A at thefront end thereof, the rod or standard 6 is turned in the requireddirection, and after the desired adjustment has been secured, the lockwasher or tail nut 12 is moved down upon the standard 6 into engagementwith the upper edge of the tubular extension 10.

15 designates a casting or bracket which is bifurcated as shown so as tofit over and upon the rear axle B at one end of the latter, said bracketbeing clipped or secured to the axle in any desired way, and 16designates a screw-threaded rod which is swiveled at its lower end, asat 17 in the upper member or cross bar of said bracket. The rod 16 hasthreaded engagement in and passes through a nut 18 mounted within arecess 19 formed in a preferably angular bracket 20 secured bYgbOltS orsimilar fastening devices to one of the rear bolster sills 21, as shown.Preferably the bracket 20 is formed with a downward extension bifurcatedat 22 to produce. brace arms 23 that are designed to straddle and engagethe rear axle B when the. bracket 20 is in its lowermost position so asto take the strain off of the bracket or casting 15 and its concomitantparts, and preferably the bracket 20 "is formed with a recess 24 toreceive and accommodate the bracket 15 whenthe parts'iare in thisposition, where-- by a very strong and stab e connection is "provided.

The screw-threaded rod '16 is formed in its uQer end with any desirednumber of open gs 25 like the openings 13 for the operating rod 14, andis also preferabl provided with a lock Washer 26, to hold 1t securely inan adjusted position.

A brace rod 27 is pivotally connected at its lower end, as at 28,between cars 29 that are formed on one of the downwardly extending armsor branches of the bracket 15, said brace rod 27 passing through a clamp30 pivotally mounted upona pin 31 projecting laterally from the outerface of the bracket 20. This clamp 30 may be tightened upon the bracerod 27 in any desired way as, for example, by means of the nut 32rovided with an operating handle or cran 33. By providing the brace rod27, the rear axle is prevented from turning when the machine is raised.

It will thus be seen that I have provided a very practical, durable andeflielent construction of device whereby the body frame-- becomingbroken or disarranged, and without interfering in any way with thethreshing device.

While the accompanying drawings illustrate what I believe to be thepreferred emodiment of my invention, it is to be understood that theinvention is not limited thereto, but that various changes may be madein the construction, arrangements and proportions of the parts withoutdeparting from the scope of the invention as claimed.
